How Many Eggs Does A Neon Tetra Lay?

The number of eggs a female neon tetra can spawn varies and ranges from 60 to 120 on average at once.

As soon as the female tetra lays the eggs, the male tetra will fertilize those eggs immediately. But don’t get your hopes up, not every egg will hatch and survive.

If you look closely only 40 to 50 of the eggs will hatch giving you nearly 30% of the baby neon tetras.

For example, if your female tetra lays 60 eggs at one time, you will have 20 baby neon tetras only as only 30% will result in viable fry.

How To Tell If A Neon Tetra Is Going To Lay Eggs?

There are certain signs your neon tetra will show if it is going to lay eggs but first you need to differentiate the male from the female tetra.

Male neon tetras have a slimmer body with longer dorsal and anal fins whereas female neon tetra has longer and slightly larger body with shorter anal and dorsal fins.

How Can You Know When The Neon Tetra Eggs Are Fertilized?

Frequently Asked Questions

Here are answers to some FAQs you might be wondering about.

Do Tetras Eat Their Eggs And Babies?

Yes, most definitely. That’s why experts suggest you keep parents separate from the eggs and the fry once they hatch.

Tetras are known to eat their eggs as well as fry mistakenly, so it is necessary to remove those adult tetras from the Tetra breeding/Fry tank.

Similarly, these sensitive small babies are prone to diseases as well as physical injuries. Adult tetras can harm these fish and even injure them while swimming around.

What Should I Feed Baby Tetras?

You can feed your baby tetras a few drops of Infusoria a few times a day. Baby shrimps can also be a good choice once they get a little older to feed on them.

What Do Unfertilized Neon Tetra Eggs Look Like?

Unfertilized eggs remain white even when all the other eggs will develop black dot inside them. It will be easier for you to distinguish between fertilized and unfertilized eggs when you look closely for the black dot inside the eggs.

The unfertilized egg might be in the same cluster but they will remain yellowish or whitish but don’t separate them.

Don’t let adult tetras feed on unfertilized eggs as well because these adults can go for fertilized eggs too when the unfertilized eggs are finished.

What Is The White Substance Neon Tetra Eggs Have Around It?

The whitish substance around the fish eggs is the fungus infecting those eggs. The fungus is the curse that attaches itself to the eggs and kills the embryo before it even gets the chance to hatch.

You can go for formalin and hydrogen peroxide to treat the fungus or else prevention is better than cure.

Keep your tank water clean and ideal for fish to breed, hatch, and live to avoid further infestation of fungus or bacteria.

Once you see tiny, round, whitish, or yellowish jelly-like balls, you will know that your neon tetras have laid eggs. Even your fish will show signs beforehand too.
